Goldtarget said:The Walbanker is similarly sized, but a sluice wont always have that sort of volume or pressure, using it as a guide and its principles will help. I have built several projects at 1200, including a sluice, but use multiple configurations depending on material and flow. The trick here (and I'm not taking a shot at the breadcrate, I've just never used it in a sluice) is to get a decent amount of liquidity happening on the slick plate, the better this happens the better the capture. Vrib and expanded (raised) do a great job and some moss is also a great option. In moderate flow with classification to 1/2 inch I would run on a1200 system at least 500 slick to 400 moss with ribbed or backed matting (the expanded if flat will be fine on is own) and 400 with riffles or expanded and moss here to if not already in it. Alot of thought goes toward no moss after slick plate but i find if you use it upfront under expanded it will capture just a much as without.
So to recap, 500 slick, 400 expanded to floor vrib or moss, then the rest either expanded or riffles over moss with vrib underneath or backed mat. That's my 2 specks worth others may disagree, but a Doc says, you can't have too many interruptions or capture points, expose the gold to as many variations as you can.
Goldtarget said:Spot on mate. The better you classify the better it will work, no question. On a capture size that your sluice has you can afford to run for some time especially if you have three backed matting. It can take a while to reach its capture limits. I'll post up a pic if i get a chance of my banker with the configuration i use so you can see what I'm saying. You'll find that most of the time your gold will be at the top section of any configuration you decide to go with. Using a bread crate as opposed to expanded and matting may be ok, but i feel like its alot to sandwich in when raised expanded will do a really good job of capturing most things and backed by matting in my experience virtually everything. Make sure your expanded is raised, and in the correct way. Good luck mate, and if anyone else wants to add their thoughts (I'm only suggesting what has worked for me) then by all means take note. Whatever you decide just do some testing until your confident and may you find a heap of it.
TenOunce Tone said:Hi Pj. You should get a nice "V" on the slick plate with the tip of the V just before the first catch area. If things are set up correctly you should find the majority of the gold dropping in the first 300 - 400 of the catch area. If you check utube you should be able to find videos on correct water flow in a sluice. Just keep in mind a river sluice wont hace the high flow a banker does. You should be aiming for about a 50mm deep (half ur depth) at the start of your catch area.
On classification size, 1/2 inch should be all you need. Unless you are using a shaker or some other assisted method. You will find it will take too much of your time to classify down to 1/4 in the field. The whole point of a RS is to process more volume of material.
Just my thoughts on it.
Good luck with it, sounds like your on a winner
Cheers, Tone
